GAS-BURNER-VFOSZITIONING MEANS.

2T0 all whom it may concern Be it known that l, HERBERT S. HUM- rrinur, a citizen of the United States, and resident of Kalamazoo, in the county of Kalamazoo and State of Michigan, have invented certain new and useful Improve ments in G-as-Burner-Positioning Means, of which the following is a specification.

Gas burners of the general type employed in instantaneous water heaters are usually so constructed as to project the flame at an angle to the vertical axis of the burner, causing the flame to play inwardly and upwardly toward the water circulating coil ordinarily located above the burner-inclosing lower portion of the heater casing. The usual practice is to removably mount the burners on a circular series of upstanding gas-delivering spuds secured to the supportforming base ring of the heater to which a gas supply pipe is connected. The burners are formed with circular spud-embracing sockets and are simply placed or set in position on the spuds. The heaters are usually shipped from the factory without having the burners mounted therein, it being left to the plumber or other person installing the heater to put the burners in place, Through ignorance or carelessness the burners are not infrequently so positioned as to project the flame outwardly against the inclosing casing, thereby destroying or seriously damaging the casing and preventing the burner from performing its coil-heating function.

The object of the present invention is to obviate this difficulty by providing means that will insure proper placing of the burners and which will render it impossible to place them other than in predetermined correct position.

In the accompanying drawings, Figure 1 is a sectional elevation of the lower portion of a water heating casing equipped with the improved burnenholding means. Fig. 2 is a sectional plan View of one of the positioned burners, taken on line 2--2 of Fig. 1. Fig. 3 is a detail view of the lower portion of the burner, Fig. 4: is a similar view of one of the gas-delivering spuds and its associated holding device. Fig. 5 is a vertical section of a portion of one of the burners and supporting means embodying a slight modification.

Referring to the drawings, 2 designates Specification of Letters Patent.

SeriaI No. 47,329.

the upright jacket-forming portion of a heater casing which is supported on base 3, and embodied in the latter is a gas-distributing ring a to which may be connected a supply pipe as indicated at 5. Tapped into the top of ring a are the upstanding gasdelivering spuds 6 usually arranged in a circular series, the upper portion of each spud being smooth and circular as indicated at 6. This smooth portion may taper upwardly as in Figs. 1 and 1-, or it may be straight or cylindrical as in Fig. 5.

The combined burner and mixer 7, usually of upright form is ordinarily provided at its upper end with a series of angularly disposed tips 8 which project the flame inwardly or toward the center of the casing and upwardly for heating the water-circulating coil, not shown. At the center of the base of each burner is a circular spud-cur bracing socket 9 which is adapted to slip down over and lit the smooth portion 6 of the spud, at the exterior of socket 9 the bottom of the burner being open for the admission of air as indicated at 9. Ordinarily the burner may be seated on a spud without regard to the direction of its gasemitting upper end so that not infrequently the burners have been so positioned as to direct the flame outwardly toward casing 2 instead of inwardly, with the disastrous consequences above noted. To forestall this, a positioning device is provided which is rigid with the burner support and which will preclude the placing of the burner in other than correct operative position.

As here embodied the positioning means consists of the arm 10 apertured to embrace the upper portion of spud 6, the opening in. the arm being preferably flat at 11 to en gage a corresponding fiat side 11 of the spud, and in addition the arm is pressed tightly into place, so that turning of the arm on the spud is precluded. The spud with the attached arm is fixed on ring l before the heater leaves the factory and hence is always in proper position. The outer end of arm 10 is turned upwardly at 10 for entering the side slot 12 in the lower portion of burner 7, the latter being ordinarily formed with a base flange 7 in which the slot is cut, the slot being so located as to register with the arm projection 10 only when the burner is in proper position. When not in register with the slot, the arm obstructs the placing of the burner on the spud, and by this means it is rendered im possible to attach the burners in other than correct position.

While designed primarily for use in water heaters, it will be understood that the invention may be made use of wherever applicable without departing from the spirit and scope of the appended claims.

I claim 1. The combination of a gas burner-heated structure, gas supply means, a plurality of separately removable gas burners seated on said means to receive their supply of gas therefrom, each burner having a certain invariable operative position with respect to said structure, and individual positioning means for each burner obstructing the seating of the burner on said gas supply means except when the burner is in said certain operative position and maintaining the burner against shifting from said position while remaining seated, substantially as described.

2. The combination of a gas burner-heated structure provided with a gas burner support, a gas burner seated on and longitudinally removable from said support and having a certain operative position with respect to said structure, and burner-positioning means providing an interlocking connection between the burner and said structure when the burner is in said certain operative position and obstructing the longitudinal application of the burner to said support whenthe burner is in any position other than said certain operative position.

3. The combination of a support, a gas feeding spud projecting therefrom, a burner having a socket adapted to removably embrace the spud, and a positioning arm rigid with the spud and adapted to interlock with the burner when the latter is in proper position and to obstruct the placing of the burnerwhen not in proper position. 4. The combination of a support, a gas feeding spud extending therefrom, a burner formed for longitudinal application to and removal from said spud, and a positioning arm arranged to interlock with the burner when the latter is in proper position and to hold the same against axial movement on said spud and to obstruct the longitudinal placing of the burner on the spud when the burner is not in proper position, substantially as described.

5. The combination of a support, a gasfeeding spud projecting therefrom, a burner having a circular socket adapted to removably embrace the spud, the exterior of the burner formed with a notch, and an angu- .lar positioning arm rigid with the spud and adapted to enter the burner notch when the burner is in proper position and to obstruct the placing of the burner when not in proper position.

6. The combination of a gas-supplying support-forming chamber, a gas-delivering spud rigid with and projecting upwardly from the chamber, an upstanding positioning arm embracing the spud and rigid therewith, and a gas burner having a socket adapted to removably embrace the spud, the burner formed with a notch to receive the upstanding arm when in proper position with the arm obstructing the placing of the burner when not in proper position.

7. The combination of a water heater casing, a gas-supplying base ring therefor, a series of upstanding gas-delivering spuds rigid with the ring, a plurality of burners having predetermined position in the easing, each burner provided with a socket adapted to removably embrace the spud, and a positioning device for each burner adapted to interlock with and permit longitudinal movement of the burner onto its spud when the burner is in said predetermined position and to obstruct the mounting of the burner on the spud when not in proper position.

8. The combination of a support, agas feeding spud projecting therefrom, a burner having a socket adapted to removably embrace the spud, the burner formed with a slot, and a positioning arm projecting from the spud and adapted to enter the slot when the burner is in proper position, the arm obstructing the placing of the burner when .the latter is not in proper position.

9. The combination of a gas burner heated structure, a gas supply device, a gas burner longitudinally applicable to said device to receive its gas supply therefrom and having a certain invariable operative position with respect to said structure, and positioning means for said burner obstructing the application of the burner to said device when the burner is in any other position than said certain operative position, and permitting application of the burner to said device when the burner is in said operative position and then maintaining the burner in said certain operative position, substantially as described.

In testimony whereof, I affix my signature.
